Abstract (en)
[origin: EP1150037A1] Lubricant retaining slits (5, --) are formed on a pair of seal members (2) from end surfaces (2b) thereof facing inside in the axial direction of a nut (1) of a ball screw to intermediate portions of the seal members (2), and foreign bodies removing slits (6 --) are formed on the seal members (2) from end surfaces (2c) thereof facing outside in the axial direction of the nut (1) to intermediate portions thereof. The lubricant retaining slits (5--) can positively trap the lubricant invading into the gap between the seal member (2) and the screw shaft and returns the lubricant inside the nut (1). The foreign bodies removing slits (6 --) can remove the foreign bodies stored on the outer peripheral surface of the screw shaft and discharged outside the nut (1). <IMAGE>
